Title: Shock absorber
Inventor: OKADA HIROSHI
IPC: F16F15/03
Filed: 2007-03-28
Abstract: <P>PROBLEM TO BE SOLVED: To reduce shock generated when a nut collides with a stopper such as a bush.  <P>SOLUTION: A damper device has a screw mechanism 30 converting linear movement into rotational movement by a ball screw. In the male screw part 32a of a screw shaft 32, the screw lead L1 formed in a neutral area A1 is formed to have the same lead as a female screw part 34a, and the screw lead L2 formed in a braking area A2 other than the neutral area is formed smaller than the screw lead L1 formed in the neutral area A1 (L2<L1). Thereby, when the nut 34 is displaced in the braking area A2, since frictional resistance between the nut 34 and the screw shaft 32 is increased in comparison with a case where the nut is displaced in the neutral area A1, the nut 34 is prevented from being largely displaced when the nut is displaced from the neutral area A1 of the male screw part 32a to the braking area A2 thereof. Therefore, the shock generated when the nut 34 collides with the bush 52 can be reduced.  <P>COPYRIGHT: (C)2009,JPO&INPIT

Title: Vibration-proof device
Inventor: SENO YOSHIYUKI
IPC: F16F15/08
Filed: 2007-03-28
Abstract: <P>PROBLEM TO BE SOLVED: To provide a vibration-proof device capable of preventing generation of noise when a vehicle is started or stopped.  <P>SOLUTION: Since the vibration-proof device is made to a constitution that an inner peripheral surface shape of a through hole 22b is formed to an elliptical shape and a long axis radial direction of the elliptical shape is directed in a vehicle longitudinal direction, a clearance between a stopper bolt 40 and the through hole 22b can be sufficiently ensured in the vehicle longitudinal direction. Thereby, even when vibration of large displacement in the vehicle longitudinal direction is input accompanying with starting or stopping of the vehicle, the stopper bolt 40 is suppressed from colliding to an inner peripheral surface of the through hole 22b, and generation of beating sound (noise) can be suppressed.  <P>COPYRIGHT: (C)2009,JPO&INPIT

Abstract: <P>PROBLEM TO BE SOLVED: To prevent Mg in a p-type clad layer from diffusing into an active layer.  <P>SOLUTION: The p-type clad layer 15 of a light-emitting diode 1 has a superlattice structure, as shown in Fig.2, in which p-InGaN layers 152 and AlGaN layers 151 are alternately laminated five times on a non-doped AlGaN layer 151a in contact with the active layer. Mg concentrations of the p-InGaN layers 152 are such that Na=Nb<Nc<Nd=Ne where the Mg concentrations of the p-InGaN layers 152a, 152b, 152c, 152d and 152e are respectively Na, Nb, Nc, Nd and Ne and they monotonously increase as coming farther away from the active layer. By thus making the Mg concentrations of the p-InGaN layers 152, the concentration of Mg diffusing into the active layer can be reduced to improve light emission efficiency.  <P>COPYRIGHT: (C)2009,JPO&INPIT

Abstract: <P>PROBLEM TO BE SOLVED: To solve various problems caused by that three-dimensional information to be used for stereoscopic display and a three-dimensional shape recognition is expressed by a coordinates system specific to an imaging system acquiring the three-dimensional information.  <P>SOLUTION: A luminance image representing the luminance value of each point captured by an imaging system when photographing a photographing space, and three-dimensional information representing the spatial position of the each point expressed by a predetermined coordinate system are acquired from the imaging system or a recording medium. An input for designating an offset value in each axial direction of the coordinate system is received from an input device, and each offset value is stored in a predetermined memory to thereby set a point obtained by displacing the origin of the coordinate system by the offset value as an offset origin. A file of a prescribed format is generated, which has an area for storing the luminance image, an area for storing the three-dimensional information, and an area (h10) for storing information of the offset origin. In stereoscopic display and three-dimensional shape recognition, the information of the offset origin stored in the file is used for coordinates conversion of the three-dimensional information before processing.  <P>COPYRIGHT: (C)2009,JPO&INPIT
